outcome of pregnancy and breast cancer

Conditions: Pregnancy; Breast Cancer

Summary: investigators are interested to explore the clinical and pathological characteristics of breast cancer with pregnancy, maternal age at the time of diagnosis of breast cancer during pregnancy, median gestational age at diagnosis, the level of the tumor differentiation patients present with, during pregnancy, and the hormonal-receptor status. investigators plan to collect prospective quality research databases that could provide further important information concerning this condition and serve in both short- and long-term sequelae in mother and fetus.

breast cancer is classified as pregnancy-associated if it is diagnosed during pregnancy or within one year of delivery . about 3% of all breast cancers are diagnosed during pregnancy . the average age at diagnosis for patients with pabc is 32-38 years .a painless mass is palpated by the patient in 90% of reported cases .the incidence of breast cancer is the same in pregnant women as nonpregnant women in the general population. breast cancer is the most common malignancy affecting women world wide. more than one million cases diagnosed annually. one in ten of all new cancers diagnosed worldwide each year is a cancer of the female breast, and it is the most common cancer in women in both developing and developed areas. it is also the principal cause of death from cancer among women globally. similar applied to saudi arabia. more over, cancer registry suggested an increase in incidence over the years with median age of 67 years old. the same applied for other arab regions. recently, women in arab regions postpone their first pregnancy which may increase the risk for pregnancy associated breast cancer. the physiologic changes that take place in the breast during pregnancy can contribute to a delay in the diagnosis of pabc. in preparation for lactation, a women's breast size will nearly double in size and weight. the influence of estrogen and progesterone cause an increase in blood flow and fat, resulting in an increase in the size of milk-producing glands. some women may begin to leak colostrum by 25 weeks gestation. irritation of the breast ducts caused by rapid tissue growth may cause a bloody discharge, which usually is a benign condition. the areola also may increase in size and become darker in color. in addition, montgomery tubercles, small nodules surrounding the areola, will produce a fluid to lubricate and cleanse the nipple in preparation for nursing. breast cancer associated with pregnancy presents to the clinician with particular challenges at diagnosis and management level. the diagnosis may be delayed and difficult owing to the physiological changes within the breast and limitations on investigations. moreover once a diagnosis has been confirmed and staging completed, options for treatment will be influenced by the need to give optimal treatment to the mother whilst minimizing risks to the fetus. the particular challenges faced both in the initial diagnosis and management of women with pregnancy-associated breast cancer will be assessed in this study. recent studies suggest that, when matched for age and stage, the prognosis of pregnancy-associated breast cancer is comparable to non-pregnancy-associated breast cancer. however, the risk for breast cancer recurrence associated with subsequent pregnancies in this population is not clear. although there is data showing no increase in the risk of recurrence for women who become pregnant after breast cancer treatment, pregnancy-associated breast cancer may be a distinct clinical category where subsequent pregnancies after treatment may confer an increased risk of recurrent disease9. there is a lack of controlled data concerning the management of pregnancy-associated breast cancer, both locally and globally. investigators plan in this study to assess and document the clinical presentation, diagnosis, treatment, prognostic factors, and routine clinical management of pregnant ladies diagnosed with breast cancer in saudi arabia. data base through data collection on all information related to breast cancer patients with pregnancy will be performed across detailed interview and chart review at all specialized clinic in the national guard. all patients seen within the coming 5 years will be enrolled in this study. investigators are interested to explore the clinical and pathological characteristics of breast cancer with pregnancy, maternal age at the time of diagnosis of breast cancer during pregnancy, median gestational age at diagnosis, the level of the tumor differentiation patients present with, during pregnancy, and the hormonal-receptor status. investigators plan to collect prospective quality research databases that could provide further important information concerning this condition and serve in both short- and long-term sequelae in mother and fetus.
